    did you intend to list the same ordered pair twice, or is this a typo?

    No two ordered pairs (i.e. different pairs) may have the same first term.
    Is that true?

    This is not a typo. The same point (10,6) is given on this list of points.

    I don't follow. Is this a function or not? If not, why not? Thanks.

    Those are not two pairs but one term written twice.

    In that case, the relation is a function, right?

    More important than knowing the right answer is knowing why the answer is right.

    So tell us, why is this relation a function?

    Each x-value is different making this relation is a function. Correct?
